GLP-1S Certificate of Analysis Results
What the GLP-1S record shows
Evidence through 2026-04-09TitrateLab tracks 8 published GLP-1S certificate-of-analysis records through 2026-04-09. Across 8 records with a usable peptide-purity result, the median reported purity is 99.8%. Across 8 records with measured-versus-label dose data, 25% are within 10% of the labeled quantity. This is a public convenience sample, not a randomized market survey; one result describes one submitted sample and does not verify other batches.
Limits and missing evidence
- No classifiable endotoxin results were recorded.
- Coverage depends on reports that were published and available to ingest.
